1 Introduction USB Ports The system board supports USB 2.0 and USB 1.1 ports. USB 1.1 suppor ts 12Mb/second bandwidth while USB 2.0 suppor ts 480Mb/second bandwidth providing a marked improvement in device transfer speeds between your computer and a wide range of simultaneously accessible external Plug and Play peripherals. BIOS • Award BIOS, Windows ® 98SE/2000/ME/XP Plug and Play compatible • Supports DMI 2.
Introduction 1 I/O Connectors • 1 connector for 2 additional external USB 2.0/1.
1 Introduction 1.1.3 Intelligence CPU Fan Protection The CPU Fan Protection function has the capability of monitoring the CPU fan when the system boots. Once it has detected that the CPU fan did not rotate, 5 warning beeps will sound then the system will automatically power-off. This preventive measure has been added to protect the CPU from damage and insure a safe computing environment.
Introduction 1 Wake-On-LAN This feature allows the network to remotely wake up a Soft Power Down (Soft-Off) PC. It is supported via the onboard LAN port, via a PCI LAN card that uses the PCI PME (Power Management Event) signal or via a LAN card that uses the Wake-On-LAN connector. However, if your system is in the Suspend mode, you can power-on the system only through an IRQ or DMA interrupt. Important: The 5VSB power source of your power supply must support ≥720mA.
1 Introduction ACPI The system board is designed to meet the ACPI (Advanced Configuration and Power Interface) specification. ACPI has energy saving features that enables PCs to implement Power Management and Plug-and-Play with operating systems that support OS Direct Power Management. Currently, only Windows® 98SE/2000/ME/XP supports the ACPI function. ACPI when enabled in the Power Management Setup will allow you to use the Suspend to RAM function.

Troubleshooting E Appendix E - Troubleshooting E.1 Troubleshooting Checklist This chapter of the manual is designed to help you with problems that you may encounter with your personal computer. To efficiently troubleshoot your system, treat each problem individually. This is to ensure an accurate diagnosis of the problem in case a problem has multiple causes. Some of the most common things to check when you encounter problems while using your system are listed below. 1.
E Troubleshooting The picture seems to be constantly moving. 1. The monitor has lost its vertical sync. Adjust the monitor’s vertical sync. 2. Move away any objects, such as another monitor or fan, that may be creating a magnetic field around the display. 3. Make sure your video card’s output frequencies are supported by this monitor. The screen seems to be constantly wavering. 1. If the monitor is close to another monitor, the adjacent monitor may need to be turned off.
Troubleshooting E Hard Drive Hard disk failure. 1. Make sure the correct drive type for the hard disk drive has been entered in the BIOS. 2. If the system is configured with two hard drives, make sure the bootable (first) hard drive is configured as Master and the second hard drive is configured as Slave. The master hard drive must have an active/bootable partition. Excessively long formatting period. 1.
E Troubleshooting Serial Port The serial device (modem, printer) doesn’t output anything or is outputting garbled characters. 1. Make sure that the serial device’s power is turned on and that the device is on-line. 2. Verify that the device is plugged into the correct serial port on the rear of the computer. 3. Verify that the attached serial device works by attaching it to a serial port that is working and configured correctly.
